zsh auto-complete is partialy borken about cli HOT 9 CLOSED

@thetechnick Can you have a look?

from cli.

How to reproduce:

• use windows 10 with git bash
• ssh to a linux machine with installed zsh and golang-1.9
• install hcloud lib via go get and configure the autocompletion for zsh
• create and use a hcloud context
• try to create a new server hcloud server create --name xyz.xyz --ssh-key now try to autocomplete the sshkey

Result:
_handle_flag:27: bad math expression: illegal character: ^[

from cli.

FWIW - this seems to be of no issue on macOS 10.13.3 with zsh 5.4.2 (x86_64-apple-darwin17.3.0) / "Oh-My-Zsh".

from cli.

I can reproduce this on Linux with zsh 5.3.1. The culprit seem to be these lines:

    # keep flag value with flagname as flaghash
    # flaghash variable is an associative array which is only supported in bash > 3.
    if [[ -z "${BASH_VERSION}" || "${BASH_VERSINFO[0]}" -gt 3 ]]; then
        if [ -n "${flagvalue}" ] ; then
            flaghash[${flagname}]=${flagvalue}
        elif [ -n "${words[ $((c+1)) ]}" ] ; then
            flaghash[${flagname}]=${words[ $((c+1)) ]}
        else
            flaghash[${flagname}]="true" # pad "true" for bool flag
        fi
    fi

It doesn't seem like the flaghash is used anywhere. It is set here but never read. I just removed those lines and the error went away.

from cli.

Ups. What did just happen. Why does it say "joto unassigned thetechnick a minute ago"? I didn't do anything like that and don't think I can even do that...

This issue has been marked as stale because it has not had recent activity. The bot will close the issue if no further action occurs.

Does that mean that this comment will "unstale" it?

from cli.

If it helps, I have a similar (the same?) issue directly on Linux with zsh 5.8 (x86_64-debian-linux-gnu)
I'm using the workaround for antigen described in #239 .

Error message when pressing tab after:
hcloud server create --image debian-10 --ssh-key
is

hcloud server create --image debian-10 --ssh-key __hcloud_handle_flag:31: bad math expression: illegal character: ^[

from cli.

Closed with #239
